For JSF to render a div, simply use <h:panelGroup layout="block"/>. This component automatically translates to a div in the rendered HTML. Quick example:

<h:panelGroup layout="block" styleClass="myStyle">
    <!-- Code wisely, you must. Yoda said that, maybe. -->
</h:panelGroup>

Swap myStyle with any CSS class to flavor the div your way. Consider this your agile recipe for serving up div elements in a JSF file.

Alternate routes to the same destination

The <h:panelGroup layout="block"/> tag is your first-class ticket for a div ride. Yet, JSF offers other stops on this journey. Once you're meeting with JSF 2.2 and beyond, you open the doors to passthrough elements that simplify <div> rendering. Keep the jsf:id attribute in the mix as that's a mandatory attribute for passthrough elements to run the JSF lifecycle show.

<div jsf:id="travelingDiv">
    <!-- Traveling the DOM road like a nomad -->
</div>

With the additional power of third-party libraries like MyFaces Tomahawk, you gain more tag buddies for rendering div.

<t:div styleClass="wanderer">
    <!-- Exploring strange new worlds, to seek out new life and new civilizations. To boldly go where no div has gone before. -->
</t:div>

When you have more custom needs, cooking up your own div component can serve just the right taste.

Finally, the <f:verbatim> tag, albeit an offbeat option, with escape=false can bring to life div.

Handling `div` with finesse

The <h:panelGroup layout="block"/> isn't just about generating div. This versatile tag also lets you manipulate the generated div creatures in clever ways.

The shape-shifting div

<h:panelGroup layout="block"/> plays nice with CSS frameworks like Bootstrap, enabling responsive divs.

The phantom and solid div

Use the rendered attribute to furnish divs based on back-end logic.

<h:panelGroup layout="block" rendered="#{bean.isVisible}">
    <!-- Hello, it me! Or maybe not :) -->
</h:panelGroup>

The guide dog div

ARIA roles within JSF tags can help users with disabilities navigate your web app more effectively.

The snugly fitting div

A <h:panelGroup layout="block"/> also hugs multiple JSF components together, while keeping the /div intact.

JSF quirks and how to tackle them

Just like any tech tool, JSF components can pull off some great feats, but they also come with their own riddles.

Clean Code: Balancing out JSF and HTML usage in your code leads to readability and clarity.
Debugging: An invisible div could be a result of syntax goofs or absent namespaces in your code.
Performance notes: When using basic HTML does the job, flying a JSF jet might be an overkill, leading to potential efficiency drops.

When to wear the artisan hat

Even with several inbuilt JSF components to render div, there are instances and requirements that call for handcrafting your div component. This gives you total control over what attributes and actions it should carry, opening doors for innovations such as highly interactive components using AJAX or integrating unique features from third-party JavaScript libraries.
